IMPROVEMENT IN BARBED FENCE-WIRES.

Specification forming part of Letters Patent No. 208,538, dated October1, 1878; application filed September 6, 1878.

To all whom it may concern.-

Be it known that I, ALBERT L. PITNEY, of Washington city, in theDistrict of Columbia, have made certain new and useful Improvements inBarbed Fence-VVire, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, and tothe letters of reference marked thereon.

Figure 1 is an elevation of a piece of barbed wire constructed inaccordance with my invention, the barb being shown in front, edge, andrear view. Fig. 2 is an elevation of the barb detached, showing it as itappears before being secured to the wire. Fig. 3 is a similar view ofthe barb as it appears after being secured upon the wire, the positionof the wire being indicated in section. Fig. 4 is a perspective view ofthe attached barb; and Fi 5, an elevation, showing a second wirecombined with the improved barbed wire.

Like letters in all the figures indicate corresponding parts.

The object of the invention is to so construct the barbed wire as thatthe barbs will not be capable of being detached under any circumstancesof ordinary usage, and so that they may be readily secured in place; andto this end the invention consists in certain peculiarities ofconstruction or arrangement, or combinations of parts, as will behereinafter first fully described, and then pointed out in the claims.

A is the fencewire, and B the barb to be secured thereto. The barb B isbent so that its pointed ends shall project outwardly in directionssubstantially parallel with its bent central portion, substantially asshown in Fig. 2. The wire A is then twisted once about the neck of thebarb, and the central portion of the barb bent down so as to clamp thewire firmly, as plainly shown in Fig. 3. By this method of uniting thebarb and wire the barb is prevented from being moved along upon the wireor revolved about it or bent down parallel with it.

I am aware that it is not new to connect the barb with the wire bybending the former about the latter, and am also aware that double wireshave heretofore been used in barbed fences.

In Fig. 5 I have shown a double wire, or a secondary wire twisted aboutmy improved barbed wire. The main barbed wire is made as in the otherfigures, and then the secondary wire twisted thereon to add strengthwhenever desirable.

For bending the barb and twisting the wire thereon, I have devisedsuitable machinery, for which I propose to make a separate applicationfor patent.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. In combination with the fence-barb havin g a narrow neck, the wiretwisted about said neck and clamped between the points and centralportion of the barb, substantially as set forth.

2. In combination with a fence-wire, a barb secured thereon bywrappingor twisting the wire about the neck of the barb, substantially as shownand described.

3. In combination with a barbed wire in which the barbs are securedthereon by twisting the main wire about the narrow neck oi the barbandclampin g the wire, as described, a secondary or auxillary wire woundabout the first, substantially as shown and described.
